Detect duplicate pages in cursor feeds

Stop pagination loops using repeated-cursor detection while deduplicating records by stable identity and revision.
Keep two independent sets
Track continuation tokens already requested and records already processed. A token loop and a duplicated record are different failures. Use the service's stable record identifier; include revision if updates to the same record must be processed separately.
Suggested algorithm
Start with an empty token set. Before each request, reject a previously requested non-empty token. For each item, process an unseen identity/revision pair once. Continue only with the next token returned by the service, without constructing or incrementing opaque tokens yourself.
Test sequence
Serve page A with records 1 and 2 and next token B. Serve page B with records 2 and 3 and next token A. The client should process 1, 2 and 3 once and report a cursor loop before requesting A again. Keep a maximum page count and elapsed-time budget as additional bounds.
Limits
Deduplication does not prove completeness. Concurrent insertions, deletions or expired cursors can still create gaps unless the API provides a stable snapshot or change-log contract. This is an original defensive pagination recipe; on a loop, preserve the last completed position and report incomplete synchronization rather than silently declaring success.
